Choose either the simplicity of full touch screen automation or the custom precision of manual knob control.

Knob control of stimulation can be both fast and precise

Quickly ramp to higher stimulation levels

Quickly reduce if the patient is uncomfortable

Fine-tune the response level

Knob control of thermal and pulsed RF provides hands-on confidence

Useful for advanced RF treatments

Two Interfaces: Graphing or One Touch

The G4 is the only RF generator that has two interfaces to suit each doctor’s preference.

Select a different interface for each setting preset

Both have large color-coded displays of all readings

Graphing Interface:

Graph Temperature and Voltage over time

Choose knob or touch screen control

Useful for advanced treatments

One Touch Interface:

Very large displays

Simplified touch screen controls

Useful in a busy practice

Cable Organizers: For Speed and Confidence

Multi-electrode procedures can be slowed if cables get tangled or electrodes fall on the floor. Only Cosman offers a comprehensive system for organizing cables and holding them both at the generator and in the surgical field.G4 Cable Organizer: Cables are captured in an autoclavable strip with tabs labeled to match the G4’s electrode jacks:

Clip the organizer to the drapes to clearly identify which cable attaches to which output jack and prevent droppage.

Clip four 3-meter cables (CB112-TC) together at both ends to keep the cables untangled, even through autoclaving.

Impedance ■ : The resistance to RF current flow of RF from an electrode.

Importance: High impedance indicates an unplugged electrode or boiling at an electrode’s tip that is unobserved due to temperature sensor malfunction. Low impedance indicates the electrode is touching a reference structure.

Voltage ■ : The generator output to an electrode.

Importance: Indicates if the generator is or is not delivering energy to an electrode.

Current ■ : The flow of RF current from an electrode

Importance: High current without temperature rise indicates a problem with the temperature measurement.

Power ■ : The rate of thermal heating at an electrode.

Importance: High power without temperature rise indicates a problem with the temperature measurement.

It is critical that all these readings are observed by the physician for each electrode for safe RF lesioning. It is NOT sufficient to have a single measurement for all electrodes since this does NOT indicate a problem with a specific electrode.

Ease of Use

The G4 generator sets the industry standard for ease of use and ergonomics. It can be fully operated using either a 12-inch (30 cm) touch screen or a wireless remote, and has knob for optional manual control. The G4’s beautiful interface is very intuitive, with color coded screens and large readings, as well as your choice of a graphing interface for advanced procedures, or a “one touch” interface with simplified controls for a busy practice. The on-board doctor and patient presets, and automatic data collection, enable true electronic record keeping.
